Back to back vs face to facebearing

We are a precision bearing company located in Houston, Texas, and the only authorized distributor of GMN precision components in the USA.

Bearing precision is important, especially if your equipment is being used at maximum speeds. Precision classes guide the properties of bearings to ensure uniformity and regulation standards are met.

Our in-house engineers at GMN Bearing USA offer best in class support to help you improve the performance of your application with proper ball bearing installation and maintenance. We work with several industries and applications including:

Includes built-in ball bearing support. Supports HEAVY loads & has a high torque capacity: 53 to 588 Nm. Bore (ID) sizes: 10 to 60 mm (0.393 to 2.362 in)

Compressed air systems form the backbone of many industrial operations. However, unnoticed leaks in these systems lead to significant losses. They affect your productivity, drain your resources, and can cost you hundreds of thousands of dollars annually. That makes compressed air leak detection and repair crucial for any business using these systems.

Includes built-in ball bearing support. Supports MEDIUM loads & low to medium torque capacity: 53 to 267 Nm. Bore (ID) sizes: 17 to 40 mm (0.669 to 1.57 in)

The best air leak detector depends on your specific application and the size of your operation. When selecting one, ensure it aligns with your plant's needs and has a good range.

Super precision bearings

We know that not every application requires super, high-precision bearings. We stock other industrial parts from quality brands.

Our GMN Gap Seals are plastic and a great choice for washdown applications, such as food conveyors and food manufacturing facilities

By measuring the flow into the distribution system when the plant isn't running until there's a 14.5 psi drop in pressure, industries can gain a realistic estimate of leakage levels.

Start by multiplying the number of compressors in operation by the amount of Kw each uses. Multiply your result by the total operating hours per year, then by the cost per kilowatt. This is assuming all the compressors run concurrently.

Our goal is to make sure every machine and application has the right precision angular contact bearing. If you are unsure about what bearing is best for your application, contact us!

We ship orders the same day the PO is sent (as long as the PO is sent by 3:30 pm CST). Most of our precision bearings are in stock and ready to ship out from Houston, Texas.

Leak detection for compressed air systems should be conducted quarterly or bi-annually. The frequency varies based on the system's age and usage patterns. Tools such as air flow meters using digital technology can run constantly and provide real-time alerts.

Wasting air is a considerable energy cost in industrial settings. Losses from compressed air leaks don’t just stem from the direct wastage of the compressed air. There's also the additional energy required to compensate for the pressure drops caused by these leaks.

Testing typically begins with high pressure as these lines are the primary sources of significant leaks. However, the exact pressure depends on the system and the standards it adheres to.

Cylindrical roller bearings

Our ABEC 7 angular contact bearings are manufactured in Nürnberg, Germany, and stocked in Houston, Texas. We have one of the largest in-stock inventories of angular contact bearings in N. America.

According to recent research, 25 to 40 percent of the world's industrial energy is lost due to leaks in compressed air systems. Globally, that adds up to billions of dollars in losses from poorly-maintained equipment.

No built-in ball bearing support. Has no RPM limits & Supports high torque needs: 609 to 14,060 Nm. Bore (ID) sizes: 38.09 to 220 mm (1.499 to 8.66 in)

Needle rollerbearing

This heavy-duty clutch (aka a hold-back clutch) is good for high torque operations and ensures motion freezes in place. Bore (ID) sizes: 15 to 40 mm. (0.59 to 1.73 in)

Angular contact bearings support both radial and axial loads and are designed to operate at high speeds for vast amounts of time. Also known as spindle bearings, GMN angular contact bearings are beneficial for applications that:

Designed with grooves in the outer ring to offer more protection (than our L-type seal) against contamination and direct spray liquids. Liquid gets pushed out through outer grooves when in rotation.

Ultrasonic detection and air flow meters are reliable leak detection methods for compressed gases. However, the “correct,” or best methods depend on the specifics of the gas being used and the system in question.

We understand that some machine applications have different and unique bearing requirements. Some may need heavier load capabilities or faster operational speeds. We strive to offer a truly customizable approach for our angular contact bearings.

Now, simply multiply that by .25 for 25 percent of your operating cost. The result is a low-end estimate of annual money wasted due to air leakage.

Thrust rollerbearing

Next, you can calculate your individual losses using your operating costs. We’ll use the low estimate that 25 percent of operating costs stem from compressed air leakage.

That's anywhere from a few thousand to nearly a million dollars in annual losses for an individual plant, brewery, or other production setting,

No built-in ball bearing support. Good for large orders & low to high torque needs: 1 to 2673 Nm. Bore (ID) sizes: 2 to 240 mm (0.078 to 9.448 in)

The best protection for your bearing. Easy to install with a simple “drop-in” next to your bearing. No added space needed. CF seals offer 100% sealing efficiency against splashing liquids.

Ultrasonic detectors, air flow meters and thermal imaging can determine where an air leak is coming from in large industrial environments. Visual checks, applying soapy water to suspected problem spots, and listening for hissing are useful in smaller settings.

Identifying and addressing air leaks promptly can save industrial setups from wasting air and escalating energy costs. It also optimizes the system's efficiency, ensures the longevity of equipment, and reduces the carbon footprint of the plant.

Fixing leaks is often a time-consuming process, especially when they've gone undetected for long. There’s also the time necessary to repair related damage.
